The mobile phone device 1 is provided with a GPS function and a navigation function for acquiring the current position, in addition to a telephone function (call function), a mail function, and an Internet connection function (Web access function). In this navigation function, a map around the current location (current location) or a map around the destination is received and output for guidance, and a route map from the current location to the destination is received and output for guidance.

  This cellular phone device 1 is located via the public mobile communication network (public mobile communication network) 2 and the management server 3 via the nearest base station 4 and exchange 5 constituting the public mobile communication network 2. A registration response is made. At that time, the cellular phone device 1 sends a reception result from the GPS satellite 6 to the management server 3 to request location information. The management server 3 carries out a mobile phone based on the GPS information. The current location of the telephone device 1 is calculated, and this calculated location is transmitted to the requesting mobile phone device 1. The management server 3 stores and manages the subscriber telephone number and mail address for each user, and periodically updates the current location information of each mobile phone device 1.

  The management server 3 also functions as a content server that provides a location information service (navigation service) that guides the route from the current position to the destination on the map, and the mobile phone device 1 is a public mobile communication network 2. Connected to the management server 3 via the navigation server 3 to receive and obtain navigation information (route map) from the management server 3, guide the route to the destination and display voice guidance such as turning left and right as necessary. I have to. As described above, the management server 3 is capable of executing various services such as navigation services in addition to the registration management of the terminal location. However, the management server 3 may of course be configured to be distributed to dedicated servers for each function and each service.

FIG. 2 is a block diagram showing basic components of the mobile phone device 1.
The CPU 11 is a central central processing unit that controls the overall operation of the mobile phone device 1 in accordance with various programs in the storage unit 12. The storage unit 12 is an internal memory, and has a program area and a data area. In this program area, a program for realizing the present embodiment according to an operation procedure shown in FIGS. Stored. The data area is provided with an address book AD, which will be described later. The external recording medium 13 is a removable portable memory that supplies various data programs such as recorded contents to the outside. The external recording medium 13 is composed of, for example, an SD card or an IC card. The memory 14 is an internal memory having a work area, and various data in the memory 14 is saved in the storage unit 12 as necessary.

  The telephone communication unit 15 takes in a signal from the reception side of a transmission / reception unit (baseband unit) connected to an antenna that constitutes a radio unit, demodulates it into a reception baseband signal, and then receives a reception speaker via the acoustic control unit 16. The sound is output from 17. Further, the telephone communication unit 15 takes in the audio data input from the transmission microphone 18 from the acoustic control unit 16, encodes it into a transmission baseband signal, gives it to the transmission side of the transmission / reception unit, and outputs the output from the antenna. . On the other hand, content (for example, map information) received and acquired via the telephone communication unit 15 by the Internet connection function or the like is given to the main display unit 20 via the display control unit 19 and displayed and output.

  The key operation unit 21 performs dial input, character input, command input, and the like. The key operation unit 21 is provided with numeric / character input keys, dial keys, a navigation button for instructing activation of a navigation function, and the like. The CPU 11 executes processing according to the key input signal from the key operation unit 21. The GPS receiver 22 receives the current position (latitude and longitude information) using the GPS satellite 6 and the ground station, and the CPU 11 periodically accesses the GPS receiver 22 to obtain the current position (terminal position). To get. The RTC (real time clock module) 23 constitutes a clock unit, and the CPU 11 acquires the current date and time from the RTC 23.

FIG. 3 is a diagram for explaining the address book AD.
The address book AD stores and manages information related to each communication partner, and includes “name”, “phone number”, “mail address”, “specific partner flag”, “attribute”, and “location information”. Each item has information that is arbitrarily set by user operation. “Name”, “telephone number”, and “mail address” are terminal identification information for identifying a partner terminal. The “specific partner flag” is a flag indicating a specific partner such as a parent to the child. In the mobile phone device 1 possessed by the child, “father”, “mother”, and “grandparent” are shown as shown in the figure. Correspondingly, “specific opponent flag (circle)” is set. In this case, at the time of route guidance, “Father” or “Mother” is selected as the specific partner, and the route to the location is guided.

 “Attribute” indicates the type of “position information” corresponding to the “specific partner flag”, and “fixed” is set if the fixed position indicates a non-moving fixed position such as a home position. If it is the position of the mobile phone device 1 possessed by the other party (current position of the mobile terminal), “move” is set. The “position information” corresponding to the “specific partner flag” is set when the “attribute” is “fixed”, and indicates a non-moving fixed position such as a home or grandparent's house. “Fixed position information (longitude and latitude information)”.

 Here, when the activation of the navigation function is remotely instructed from the specific partner terminal such as the parent to the mobile phone device 1 possessed by the child, the CPU 11 acquires the position information determined according to the partner and obtains the navigation function. It is set as a destination. That is, when communicating with the communication partner via the telephone communication unit 15 (for example, when the line is cut off after receiving a call or when the line is cut off after calling), the CPU 11 indicates that the other party's phone number is “specific partner flag. If it is a "telephone number" corresponding to the specific partner, that is, at the end of a call with the specific partner, the "location information" When the “attribute” is “fixed”, the corresponding “fixed position information” is read out from the address book AD and used as the destination of the navigation function. The terminal function is received and the navigation function is operated (for example, activated) as a destination of the navigation function.

  Next, the operation concept of this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, an operation peculiar to this embodiment can be executed by using a program / data supplied externally via a transmission medium.

4 to 7 are flowcharts showing the overall operation of the mobile phone device 1 that is started to be executed when the power is turned on.
First, in the mobile phone device 1, the CPU 11 activates the telephone communication unit 15 to perform standby processing for registering the current position (step A1 in FIG. 4), and checks whether there is an incoming call (step A2). A standby state is entered while checking the presence or absence of any operation (step A3). In this standby state, when it is detected that there is an incoming call (YES in step A2), an incoming call notification for generating and outputting an incoming melody is performed, and a call process is executed according to the line connection with the other party (step A4). .

  Thereafter, when it is detected that the call has been terminated (line cut-off) (YES in step A5), it is checked whether or not “remote code” has been added to the current incoming call (step A6). This “remote code” is used to remotely instruct the automatic activation of the navigation function from an external terminal. For example, the activation of the navigation function is remotely instructed from a specific partner terminal such as a parent to the mobile phone device 1 possessed by the child. When the remote code “777” added to the outgoing call signal is added before the telephone number on the incoming call side (YES in step A6), the CPU 11 The address book AD is searched based on the “telephone number” of the communication partner), and it is checked whether the remote instruction is sent from the specific partner by checking whether the “specific partner flag” is set corresponding to the partner (Step A7).

  If it is not a remote instruction from the specific partner (NO in step A7), the standby state is returned to invalidate this instruction (step A1), but when a remote instruction is received from the specific partner (in step A6) (YES), referring to the address book AD, the “attribute” corresponding to the specific partner is checked (step A8), and it is checked whether “fixed” or “move” is set (step A9). If the “attribute” of the specific partner is “fixed”, the navigation function (navigation application) is activated (step A10), and then the “fixed position information” corresponding to the specific partner is read from the address book AD (step S10). A11), this “fixed position information” is set as the destination of the navigation function (step A12).

  Then, the process moves to navigation processing for acquiring and displaying a route map from the current position to the destination (steps A13 to A17). That is, the current position is received and acquired from the GPS receiver 22 (step A13), the route map from the current position to the destination is requested to the management server 3 (step A14), and in response to this request When a route map is received and acquired from the management server 3 (step A15), this route map is displayed on the navigation screen (step A16). Then, the current position and the position of the destination are compared, and it is determined whether they are almost the same, that is, whether the destination has been reached (step A17). If the destination has not been reached (NO in step A17). Returning to step A15, the above operation is repeated until the destination is reached. If the vehicle arrives at the destination (YES in step A17), the process returns to the standby state described above (step A1).

  If the “attribute” of the specific partner is “move” (NO in step A9), the flow proceeds to the flow of FIG. 5 and the navigation application is started (step A18). Is acquired (step A19). Then, a route guidance request from the terminal position of the terminal to the terminal position of the partner is transmitted to the management server 3 together with the terminal position of the terminal and the telephone number of the partner (step A20). Thereby, on the management server 3 side, a route map creation process (the flow of FIG. 8) described later is executed in response to the route guidance request.

  When receiving the route map from the management server 3 (step A21), the cellular phone device 1 displays the route map (step A22). This route map is such that the route from the current location to the opponent's position is displayed in an animation style with contents that can be easily understood by an infant. Thereafter, until the navigation end instruction operation is performed (step A23), the process returns to the above-described step A19, and thereafter, the above-described operation is repeated while sequentially transmitting the terminal position that changes every moment. When an instruction to end navigation is given (YES in step A23), a navigation end request is transmitted to the management server 3 (step A24).

FIG. 8 is a flowchart that is started when the management server 3 receives a route guidance request from the mobile phone device 1.
First, when the management server 3 receives the current location of the request source and the telephone number of the other party (step B1), the management server 3 determines the current position of the other party terminal based on this “phone number” and the base station of the “phone number” of the other party. After calculation from registration (step B2), an optimum route from the current position of the request source to the current position of the opponent is calculated (step B3). Then, after creating a route map from the current location of the request source to the current location of the other party (step B4), this route map is transmitted to the mobile phone device 1 of the request source (step B5). Thereafter, until a navigation end instruction is issued from the request source side (step B6), the process returns to the above-described step B1, and the operation of creating a new route map from the constantly changing position information and sequentially transmitting to the request source is repeated.

  On the other hand, if any operation has been performed (YES in step A3 in FIG. 4), whether the “navigation button” instructing activation of the navigation function has been operated (step A25 in FIG. 6), It is checked whether it has been operated (step A36). If it is any other operation (NO in step A36), for example, a mail creation process is executed as a process corresponding to the operation (step A37). When the “button” is operated, the navigation application is activated (step A26), and then it is checked whether or not the “kids mode” is set (step A27). This “Kids Mode” is an operation mode that makes it easy for children to use the navigation function. Parents and others operate the mobile phone device 1 owned by the child when they go out and set it to “Kids Mode”. Keep it.

  Now, when the “navigation button” is operated in the state where “kids mode” is released (NO in step A27), the process proceeds to the next step A28, and guidance indicating that the destination should be arbitrarily selected. Is displayed. When an arbitrary destination is selected and specified in accordance with this guidance (step A29), it is set as the destination of the navigation function (step A30). When selecting an arbitrary destination, a desired map may be acquired from the management server 3, and an arbitrary destination may be pointed (marked) on the map. When the destination is set in this way (step A30), the navigation processing for obtaining and displaying the route map from the current position to the destination is performed (steps A13 to A17) as described above.

  When the “navigation button” is operated in the state set to “kids mode” (YES in step A27), the address book AD is searched, and all the partners whose “specific partner flag” is set are searched. Is read and displayed on the menu (step A31). In the example of FIG. 3, the “name” or “caricature” of the father, mother, or grandparent is displayed in the menu, and when an arbitrary partner is selected from the menu (step A32), the “phone” corresponding to the selected partner is displayed. After reading the “number” from the address book AD and making a call (step A33), a call process is performed according to the line connection with the specific partner (step A34).

  Thereafter, when the end of the call (line interruption) is detected (YES in step A35), the process proceeds to step A8 in FIG. 4, and if the “attribute” corresponding to the specific partner is “fixed” as described above (in step A9). YES), the “fixed position information” is set as the destination, and the navigation processing for displaying the route map to this destination is executed (steps A10 to A17). If the “attribute” is “movement” (NO in step A9), a route guidance request to the specific partner's terminal position is made to the management server 3, and a navigation process for displaying the route map received from the management server 3 is executed in response to the route guidance request. (Steps A18 to A24).

  On the other hand, when the “telephone call button” is operated (YES in step A36), the flow proceeds to the flow of FIG. 7, and when the caller is arbitrarily selected by the user operation (step A38), the selected caller is selected. The “telephone number” is read from the address book AD and is transmitted from the telephone communication unit 15 to the telephone number (step A39). As a result, call processing is executed according to the line connection with the other party (step A40). After that, when the end of the call (line interruption) is detected (YES in step A41), the address book AD is referred to and the current caller is the specific caller for which the “specific caller flag” is set (step A42). Check whether the Metropolitan Police Department (call 110) (step A47), otherwise return to the standby state (step A1 in FIG. 4), if it is a specific partner (YES in step A42), this specific partner's The management server 3 is requested to search for the terminal position (current position) of the other party by “phone number” (step D43).

FIG. 9 is a flowchart that is started when the management server 3 receives a partner position request from the mobile phone device 1.
First, when the management server 3 receives the “telephone number” of the partner transmitted from the mobile phone device 1 together with the partner location request (step C1), the management server 3 determines the current location of the partner terminal based on the “telephone number”. Calculation is made from the base station registration of the other party's “phone number” (step C2). In this case, on the management server 3 side, the registered content (base station area) registered for each telephone number is referred to, and the base station 2 registered in association with the other party (telephone number) is specified. Obtained as the current position of the opponent.

  As a result, it is checked whether or not the partner's current position could be specified based on the presence / absence of registration of the base station area where the partner is located (step C3), and the partner base station area is not registered. When the partner position cannot be specified (YES in step C3), the partner position acquisition impossibility is transmitted to the requesting mobile phone device 1 (step C4), but the partner base station area is registered. When the partner position can be specified (NO in step C3), the partner's current position is transmitted to the requesting mobile phone device 1 (step C5).

  When the mobile phone device 1 receives the partner position from the management server 3 side (step A44), it acquires its own current position from the GPS receiver 22 (step A45), and the distance between the current position and the partner position is obtained. (Linear distance) is calculated (step A46). Then, it is checked whether the separation distance is within a predetermined distance (for example, 1 km) (step A47). If it exceeds 1 km, the standby state is returned (step A1 in FIG. 4), but if it is within 1 km (step A47). 5), the process proceeds to the flow of FIG. 5 described above, a route guidance request to the specific partner terminal position is made to the management server 3, and the route map received from the management server 3 in response to this route guidance request is displayed. The navigation process is executed (steps A18 to A24).

  If the current calling party is the Metropolitan Police Department (110 notification) (YES in step A48), the current position is acquired from the GPS receiver 22 (step A49), and is located in the vicinity of the current position. The management server 3 is requested to search for a police box (step A50). When an alternating position is received from the management server 3 in response to the search request (step A51), the navigation application is activated (step A52), and after setting the alternating position as the destination of the navigation function (step A53), In the same manner as described above, the process moves to a navigation process for acquiring and displaying a route map from the current position to the destination (steps A13 to A17 in FIG. 4).

 As described above, in this embodiment, when the CPU 11 communicates with the communication partner via the telephone communication unit 15 (for example, when the line is disconnected after the incoming call or when the line is disconnected after the outgoing call), the CPU 11 Since the location information determined correspondingly is acquired and the navigation application is operated using this location information as the destination of the navigation function, even users who are unaccustomed to using the navigation function (the elderly, children, etc.) Therefore, it is possible to guide an appropriate destination and to greatly reduce the operational burden.

  When the remote terminal is remotely instructed to start the navigation function by communicating with the communication partner, the position information determined according to the partner is acquired, and the navigation application is automatically started using this position information as the destination of the navigation function. As a result, no operation is required, and a user who is not familiar with the operation can use the navigation function.

  When the activation of the navigation function is instructed remotely, the CPU 11 refers to the address book AD and activates the navigation application on the condition that the instruction is a remote instruction from the partner terminal in which the “specific partner flag” is set. Therefore, even if a remote instruction is received from a useless party, it can be canceled.

 Under the “Kids Mode”, when the navigation button that activates the navigation app is operated and a communication partner is arbitrarily selected, the location information determined according to that partner is acquired. Even users who are unfamiliar with the operation need only to operate and select the other party. The navigation function can be used, and you can freely select the other party you want, such as selecting a father or mother. It becomes possible.

  The CPU 11 refers to the address book AD, checks the “attribute” of the “position information” of the other party, reads out the “position” when it is “move”, and reads the terminal position (the current position of the other party terminal based on the other party's telephone number). After requesting the management server 3 to search for the position), the location information of the partner terminal is received from the management server 3, and the navigation application is started with the partner terminal position as the destination of the navigation function. Since it was made to do, even if it is a mobile body like the mobile telephone apparatus 1, not only the positional information registered previously, the present position of the other party terminal can be acquired easily.

 In this case, the CPU 11 compares the terminal position of the other party acquired from the management server 3 with its current position, calculates the separation distance thereof, and starts the navigation application according to the separation distance. Even if the destination is not set by a user operation, guidance to an appropriate partner position is possible according to the distance from the current position.

 The CPU 11 refers to the address book AD, and if the “attribute” of the “position information” of the partner is “fixed”, the corresponding “fixed position information” is read from the address book AD so as to be the destination of the navigation function. Therefore, for example, if “home position”, “grandparent's house position”, etc. are registered in advance, the fixed position information can be obtained quickly and reliably.

  When the calling party of this time is the Metropolitan Police Department (110 notification), the management server 3 is requested to search for a police box located in the vicinity of its current position, and in response to this search request Since the police box position is received and acquired from the management server 3, guidance to the nearest police box is possible in the case of a lost child or the like.

  In the embodiment described above, the navigation application is automatically activated with the location information determined according to the other party as the destination when the line is cut off after the incoming call or the line is cut off after the outgoing call. During the call, the navigation application may be automatically activated with the position information determined according to the other party as the destination. Further, when there is an incoming call or outgoing call during a navigation operation in which the navigation application is activated by a user operation, position information determined according to the other party may be guided as a destination.

  In the above-described embodiment, the route map to the partner position is acquired and guided according to the positional relationship with the partner terminal position, but this route map is also transmitted to the partner terminal for display. By doing so, it is possible to approach each other while looking at the terminal screen, and it is possible to meet efficiently.

  In addition, prior to the automatic activation of the navigation application, a confirmation message inquiring whether the activation is necessary is displayed, and if the navigation application is activated under the condition that the activation is instructed by the user, the user's intention is reflected. It is possible to prevent useless activation.

  In addition, the route to the partner position is not limited to the case where the route to the partner position is guided according to the positional relationship between the terminal position of the partner terminal and the terminal position of the partner. Then, the estimated required time from the terminal position of the terminal to the terminal position of the partner may be calculated, and the estimated required time may be guided along with the route.

Furthermore, the predetermined distance (1 km) compared with the separation distance between the terminal position of the self and the terminal position of the partner may be arbitrarily set without being a fixed value.
In addition, the present invention is not limited to a mobile phone device with a navigation function, and can be similarly applied to a mobile terminal device such as a PDA with a navigation function, an electronic camera, an electronic watch, and a music player.
